How to Tell if a Diamond is Real or Fake?
Sun Mar 31 2024
Purchasing a diamond is a big decision and it takes some time to find one that better suits your needs. Diamonds are symbols of love and commitment and being a precious stone, they are also considered a symbol of luxury and status.
Diamonds are one of the easiest precious stones to fake or imitate. Also, several gemstones, like moissanite and white sapphire, look exactly like diamonds. Therefore, it is essential to ensure that the one you choose is really a diamond. A close examination of the properties of real diamonds is the simplest way to understand their genuineness.
Are you curious about how to tell if a diamond is real? Read on to learn about some easy diamond tests to determine their authenticity.
How to Determine If Your Diamond Is Real?
A question that frequently crosses the mind of every diamond enthusiast is, “How can I tell if a diamond is real?” While it is better to seek the help of an expert for accurate results, you can try some simple diamond tests by yourself to determine the authenticity of your gemstone.
If you are concerned about how to tell if a diamond is real, here are some methods you can try easily.
1. Water Test
The water test is one of the simplest and most natural diamond tests to verify the authenticity of your gemstone.
- Take a glass full of water and gently drop the diamond into it.
- Check if the diamond sinks in the water or floats on the surface.
- You can understand that your diamond is most likely to be real if it sinks in the water, as diamonds have a higher density. If it floats, it is more likely to be a fake diamond.
An important aspect to consider while performing the water test method is that you can only conduct this test on loose diamonds. Regardless of whether the diamond is real or fake, if it is set in metal, the result cannot be accurate because the weight of the metal causes it to sink.
2. Fog Test
The fog test is another relatively simple diamond test to distinguish between real and fake diamonds.
- Take the diamond in your hand and breathe air into it for a few seconds.
- If your diamond is real, the fog formed on it will dissipate immediately. However, if the fog lasts for a few seconds, the diamond will likely be fake.
3. Dot Test
Are you trying to find out how to tell a real diamond by eye? The dot test helps you easily differentiate between a real diamond and a fake one.
- To conduct the dot test, take a piece of white paper and draw a small dot on it.
- Place the diamond on the dot in an upside-down manner so that the flat surface of the diamond faces the paper.
- Look through the pointed surface of the diamond to see if you can see a reflection through the diamond.
- If a circular reflection is visible when you look through the diamond, you can understand that the diamond is fake. However, if you cannot see anything through the diamond, it is most probably a real one.
The idea behind the dot test is that real diamonds refract light in different directions rather than in a straight line, making it impossible for you to see the reflection through them.
4. Scratch Test
This is another diamond test that helps answer the question of how to test a diamond at home.
- Take the diamond and scratch it with a piece of glass.
- Examine closely to see if there are any scratches on the stone.
- If there are scratches in the diamond, you can conclude that it is fake. This is because real diamonds are resistant to scratches.
5. Thermal Conductivity Test
You can tell the difference between a real diamond and a fake one by examining how well they conduct heat. Diamonds are known for their high thermal conductivity, and this property can be used to distinguish between original and fake diamonds.
- To perform this test, take a thermal conductivity probe and place it in contact with the diamond.
- If the diamond is real, it immediately disperses the heat. On the other hand, if the gemstone disperses heat relatively slowly, it cannot be a real diamond.
Though not a completely reliable method, this is one of the simplest techniques that helps you understand if your gemstone is a real diamond or not.
6. Black Light Test
If you have a black light with you, this is one of the best diamond tests you can easily perform.
- Keep your diamond under UV light, also known as black light, and notice the glow of the diamond.
- Diamonds usually glow blue, though it is possible to have a yellow, green, white or red glow as well. Therefore, if it emits a blue light, you can take a step towards confirming that it is a true diamond.
- If it emits a different coloured light, consider ensuring the authenticity of your diamond with the help of a professional.
7. Magnetic Test
The magnetic test works on the non-magnetic properties of diamonds.
- Hold the gemstone near the magnet and examine if it gets attracted.
- If it attracts, it is certain that the gemstone is not a pure diamond. Even if it does not attract, you cannot ensure that the gemstone is a real diamond.
This is just one of the primary methods you can try at home to know if the diamond is real or fake. Seeking an expert opinion is the ultimate way to determine the authenticity of your diamond.
8. Flashlight Method
Do you know how to tell if a diamond is real using the flashlight technique? It is as simple as flashing a light near your gemstone and observing the light reflected. If your diamond is real, it will shine brightly and reflect white light and rainbows. It is unlikely that a fake diamond will reflect much light.
